ISG's 2026 assessment recognises Mastek's capability across the priorities shaping UK public sector delivery IT services today: modernisation, AI and automation, cloud, managed services, and citizen-centred design. Select a tile below to see how each area comes to life.
Applying AI where it actually improves services
Public sector AI-enabled transformation, intelligent automation, machine learning, and data platforms — built on strong data foundations that support better decisions, not just better dashboards.
"Mastek accentuates UX, service design and practical usability when developing digital solutions for the UK public sector."
- ISG
Modernising legacy systems without disrupting essential services
Public sector digital transformation through Cloud-native modernisation, application transformation, API-led integration, and agile engineering - designed around the citizen, not just the tech stack.
"Mastek boasts experience in integrating legacy systems with modern applications using APIs and interoperable architectures."
- ISG
Reliable, secure, ready for what's next
End-to-end application management, cloud adoption, and secure delivery - with risk and operational controls built in, not bolted on.
"Mastek incorporates security considerations into technology delivery, including secure application development, risk management and operational controls."
- ISG
Designed around people, communities, and place
User-centred service design, modernisation, and data-led operational improvement - built for the complexity of multi-agency, multi-stakeholder delivery.
"Mastek understands the complexities of interconnected public sector environments involving multiple agencies, service providers and stakeholder groups."
- ISG
"Congratulations to Mastek on its growing impact across the UK public sector. Its combination of government-domain knowledge, digital engineering, cloud, data and AI capabilities positions Mastek as a strategic enabler for the UK’s drive to modernise mission-critical services and deliver greater value, resilience and accessibility for citizens."
Why This Matters Now
Public sector is moving from pilots to production
ISG's research points to a shift toward scaled, structured delivery - greater reuse, stronger cyber resilience, responsible AI, and services judged on measurable outcomes rather than one-off pilots.
That shift demands more than point solutions. It requires a partner who can modernise, integrate, operate, and continuously improve public services - together. That's what Mastek's four areas of leadership add up to.
